Inter Milan striker Romelu Lukaku was also racially abused by Cagliari fans during a Serie A match last week, and Sterling says things must change.

He told Sky Sports News: "It's easy to say what happens next but there's a lot of people behind a computer screen. Those are the ones that are disappointing and feel they can get away with stuff like this.

"We are in 2019 and we're still talking about this. I can't say I have the answer to stop it but as a society we need to nail down on this.

"The people doing it need to wake up and understand it's a new era and discrimination is not something anybody should face.

"We need to grow up as a society and realise we're only out here doing our jobs. We are human beings and we have feelings.

"It's a touchy subject but I can't tell you I've got the exact answer. But as a society we need to do better and appreciate each other more."

Sterling has been outspoken in calling out racism during his career, and called for Montenegro to be handed a stadium ban after he was one of a number of England players to be racially abused during the team's win there last season.

"For me, it's too easy to do whatever you like on the internet," Rashford said. "Any of us now could go on and create accounts and write what we want under anybody's posts and nobody would ever know.

"The solution is easy to figure out - if you had to show identification to create an account that means everybody can only have one account.
